Practical & Legal
Apostille
Also known as: Apostille Stamp, Apostille Convention, Hague Apostille
The Apostille Convention (formally the 1961 Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents) replaced the slow chain-of-legalisation process — where documents had to be authenticated by the issuing country's foreign ministry, then by the receiving country's embassy or consulate — with a single standardised certificate.
The apostille itself is a printed or stamped certificate (or electronic equivalent under the e-APP — electronic Apostille Programme) issued by a designated Competent Authority in the issuing country. The form has 10 standard fields including the issuing country, the signatory, the date, and a unique reference number. Once apostilled, the document is automatically recognised in any other Convention party without further authentication.
Who issues apostilles in major countries:
• United States — the US Secretary of State (federal documents) or the relevant State Secretary of State (state documents — birth certificates, marriage certificates, diplomas).
• United Kingdom — the FCDO Legalisation Office.
• Spain — the Ministerio de Justicia (judicial documents) or the Ministry of Foreign Affairs (administrative documents).
• Portugal — the Procuradoria-Geral da República (judicial) or the Ministry of Foreign Affairs (administrative).
• Italy — the Procura della Repubblica (judicial) or the Prefettura (administrative).
Countries NOT party to the Apostille Convention require traditional consular legalisation for documents to be recognised. Notable non-parties as of 2026: Canada (joined 2024 — most provinces now apostille), much of Sub-Saharan Africa, parts of the Middle East. Check the HCCH website for the current status before assuming apostille suffices.
For expats, apostilles are needed in the following common scenarios:
• Visa applications — birth certificate, marriage certificate, criminal-record certificate (US: FBI Identity History Summary; UK: ACRO certificate).
• Citizenship by descent — the bridging-generation civil records (births, marriages, deaths).
• Marriage abroad — apostilled birth certificate and "freedom to marry" certificate.
• Academic credential recognition — apostilled diploma and transcript.
Processing times vary widely: US state-level apostilles typically take 1-4 weeks; the UK FCDO offers same-day or 2-day options; Italian Prefettura processing can take 2-4 weeks. Many apostille services exist as commercial intermediaries that handle the process for $50-$200 per document.

Hague Conventions
The Hague Conventions are a series of multilateral treaties developed by the Hague Conference on Private International Law (HCCH) governing cross-border legal matters: child abduction, adoption, civil-procedure cooperation, document authentication (Apostille), and international child support. The most-cited expat-relevant ones are the 1961 Apostille Convention, the 1980 Child Abduction Convention, and the 1993 Adoption Convention.
Notarization
Notarization is the formal certification of a document or signature by a notary public, granting it official evidentiary weight. The civil-law notary system (most of Europe, Latin America, Japan) uses highly trained legal professionals who draft documents and verify identities; the common-law notary system (US, UK common-law) uses notaries who simply witness signatures with limited authentication scope. Notarized documents typically need apostille for cross-border use.
Citizenship by Descent
Citizenship by descent (jus sanguinis, "right of blood") is the acquisition of citizenship through ancestry rather than birthplace or naturalisation. Generation depth, paperwork, and timeline vary wildly: Italy historically allowed unlimited generational descent (now restricted by the March 2025 reform); Ireland allows three generations; Germany, Hungary, Poland, Portugal Sephardic, and Spanish Sephardic each have specific routes. Often the fastest non-investment route to a second EU passport.
